honda turbo pistons need info
 

i recently purchased a 99 civic b16a2 turbo in short it melted rings so i have new pistons but they have 12:1 compression ratio can anyone tell me will these pistons work or am i mad the car has most basics needed 3 bar map sensor front mount intercooler,high flow fuel pump,full race exh manifold back,high performance clutch, dont know if ecu was modified it is standard ecu.i think it was boosting about 9 psi before detonation any info given will be appreciated

usually people put in 8.5 or 9:1 pistons in when they boost. people also use stronger rods when they put pistons in. the reason for detonation could have been your tune. did you have it tuned by a person who knows what they are doing? im confused about your emanage system. you said you were running the stock ecu? this is a problem. you need to either run a standalone system i.e. aem ems or a piggyback system i.e. hondata, crome, uberdata
